Setting fields values base on two other fields - similar to impact & urgency sets priority

[marcone]

Hi

I would like to set one field base on the values of two other fields. Similar to when impact and urgency is selected on a incident form it sets the priority.   I have 3 fields on a form A, B and C. I would like to set C based on the values set by the user in fields A and B, after I have done some processing.

I know the logic of what needs to be done but don't know how/where to put the logic in ServiceNow - is it Client script, business rules etc.

Can someone provide me with some guidance please?

Hi Sumeet

Just wanted to say thanks for your suggestions with this issue. I have managed to achieved what   I wanted to using Client scripts.
